You'll be happy when you do.  This machine runs NetBSD very well, and it's
a decent performer.

Nope, it doesn't have one.

3*6?  I don't actually know.  But if you think that's bizzare...

You want sd(0,30,1)  Partition 2 is for booting sun4c machines, but
partition 1 is for sun4 machines.

Also, the normal first tape is st(0,28,0) in case you ever need it.

It's like all the other sun4 (not sun4c or sun4m) machines in these
regards, as far as I can tell.

Odd, yeah, but at least SCSI ID 0 is sd(0,0,0)...  :)

Good luck!
